Yes, I was using compiz. Unfortunately disabling it didn't help. Power cable or brightness applet makes no difference.
I've found that I can manually change the brightness settings: > echo 2 > /sys/class/backlight/acpi_video0/brightness However, the backlight doesn't change, although the change is reflected here: > cat /proc/acpi/video/GFX0/DD04/brightness levels: 35 45 60 70 80 90 current: 60 I'm guessing this means it's a driver issue. -- brightness hardware control on Samsung R510 doesn't work https://bugs.launchpad.net/bugs/297962 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
